METHOD FOR EFFECTIVE SEPARATING FERROUS METAL FROM COAL BOTTOM ASH

摘要

PURPOSE: A method for efficiently separating an iron oxide contained in the floor material of a thermoelectric power plant is provided to improve the separating efficiency of the iron oxide using a wet type magnetism separator. CONSTITUTION: Floor ash is generated by the incineration of briquette in a thermoelectric power plant. The floor ash is introduced into a dryer. The dryer dries the floor ash(S10). The floor ahs is pulverized as much as the size of 0.15mm using a pulverizer(S20). The magnetic force strength is adjusted between 200 and 2000gauss using a wet type magnetism separator. An iron oxide is separate(S30).
